Background
Liver transplantation is an effective therapeutic option for an assortment of acute and chronic
hepatic disorders that lead to end stage liver disease in the pediatric population. According to the
practice guideline of the American Association for the Study of Liver Diseases (AASLD),
pediatric liver transplants account for ~7.8% of all liver transplants in the United States.1 The
evaluation of children for liver transplants should include a multidisciplinary team of specialists
that achieve psychosocial, neurocognitive, and developmental needs as well as the complex
clinical necessities of these patients.

For adult liver transplants (and children ≥ 12 years of age), the Model for Endstage Liver
Disease (MELD) formula is commonly utilized to determine assess organ allocation for liver
candidates. The Pediatric Endstage Liver Disease (PELD) score was analogously developed for
children < 12 years of age and utilizes total serum bilirubin INR, height, weight and albumin;
however this scoring system is not ubiquitously utilized.1

Common indications for pediatric liver transplants are acute liver failure, biliary atresia and other
cholestatic diseases, metabolic diseases, immune disorders, and hepatic malignancies. A recent

multicenter analysis of 5 year survival of 461 children revealed the first year survival rate to be
88%.5 The majority of these children also show strong graft function at 5 years, but there are
multiple chronic post-transplantation complications in extrahepatic organs.5
